Question

Reduce the proposition using laws.

Simplify ¬¬q∧T to q

 

 

**Instructions:**

1. Select a law from the right to apply to the expression: ¬¬q ∧ T

**Laws:**

- **Distributive:**
  - (a ∧ b) ∨ (a ∧ c) ≡ a ∧ (b ∨ c)
  - (a ∨ b) ∧ (a ∨ c) ≡ a ∨ (b ∧ c)

- **Commutative:**
  - a ∨ b ≡ b ∨ a
  - a ∧ b ≡ b ∧ a
  
- **Complement:**
  - a ∨ ¬a ≡ T
  - a ∧ ¬a ≡ F

- **Identity:**
  - a ∧ T ≡ a
  - a ∨ F ≡ a

- **Double negation:**
  - ¬¬a ≡ a
